MATTRE SS.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed May 11, 1907. Serial No. 373.126

To all whom it may concern:

Be it known that I, WILLIAM F. WYMAN,

a citizen of the United States, and resident of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Mattresses; and I do hereby declare that the following is a full, clear, and exact description thereof.

The improvements consist in what is herein shown, described and claimed; the object of the invention being to provide mattresses and the like having simple economical ventilators and absorbent-pads for disinfectant or insecticide fluid material.

Figure 1 of the accompanying drawings represents a sectional view of a fragment of a mattress, cushion or the like and illustrates a ventilator and absorbent pad in connection therewith; Fig. 2, an elevation of what is shown in the view aforesaid, the mattress being partly torn and the ventilator partly broken away; Fig. 3, a perspective view of a detail of the ventilator, and Fig. 4, a similar view of another detail of said ventilator.

Referring by letter to the drawings, A indicates the covering of an upholstered mattress, cushion or the like and B the filling of same. Facing the outside of an edge of the cover is a sheet-metal disk C having a central inwardly flanged preferably circular o ening.

The flange b of the disk C extends t rough registering openings in the mattress-cover and another sheet-metal disk D that faces the inside of said cover, said flange being turned-on the latter disk to fasten both disks in place. A rim-flange c of the inner disk is turned on an adjacent piece E of wire-gauze that is preferably dished within the confines of the flange b of the outer disk, the construction and arrangement of parts thus far specified constituting a ventilator. However any sides of its cover one disk having a suitable foraminous material other than wire-gauze may serve. as the air-strainer element of the ventilator.

The mattress or its equivalent may be provided with a plurality of ventilators in any suitable arrangement.

Fastened in the mattress in opposition to the ventilator is an absorbent pad that preferably consists of a bag F of cheese-cloth or other suitable fabric having a filling G of absorbent cotton or other suitable material, but any absorbent ad device is within the scope of my invention and the sameis intended to be charged from time to time with disinfectant or insecticide fluid through said ventilator.

I claim:

1. An.upholstered mattress or analogous device provided with a ventilator comprising a pair of sheet-metal disks opposing op osite ange adjacent to a central opening therein extended through said cover and a corresponding opening in the other diskon which it is turned, and a piece of suitable foraminous material held in place by a rim-flange of the inner disk turned thereon.

2. An upholstered mattress or analogous device provided with a ventilator, and an absorbent pad fastened to the mattresscover back of the ventilator through which it is accessible.

In testimony that I claim the foregomgI have hereunto set my hand at OSl1kOSl1 1I1 the county of Winnebago and State of Wisconsin in the presence of two witnesses.

WILLIAM F. WYMAN.
